In this research, the growth and metabolic activities of Saccharomyces cerevisiae immobilized in alginate gel during alcoholic fermentation with different initial glucose concentration were studied. Starting from initial glucose concentration at 140 g/L, we observed that increasing this concentration to 220 g/L had little effect on the growth of immobilized yeast. Under the same conditions, the maximum biomass, glucose uptake rate, and final ethanol concentration obtained in the immobilized yeast cultures were always higher than those in the free yeast cultures....
The production of free radicals (ROS) is an unavoidable consequence of life in an
aerobic environment. Free radicals produced from the metabolic activities of oxygen
attack biological membranes and lipoproteins via oxidation in a process called
lipid perioxidation. This attack damages cells and lipids often in a chain reaction
with carbon-based molecules such as polyunsaturated fatty acids (PUFA) in a reaction
with molecular oxygen. This creates oxidative stress and damage to tissues.
Free radicals also damage chromosomal DNA.
The aim of this study was to assess the effects of Pomelo (Citrus grandis (L.) Osbeck) peel extracts (CGE) on activity of lipid-carbohydrate metabolic enzymes such as Carnitine pamitoyl-transferase (CPT), lipase, hexokinase, glucose 6-phosphatase and blood lipid glucose parameters in experimental obese and diabetic mice. The results showed that, in the experimental obese mice treated daily, orally with CGE at dose of 1200 mg/body weight for three weeks,
I am very grateful to the special group of distinguished scientists who made up the Panel
and Secretariat for this major review of the evidence on food, nutrition, physical activity
and cancer. The vision of WCRF International in convening this Panel and confidence in
letting a strong-willed group of scientists have their way is to be highly commended.
In our view, the evidence reviewed here that led to our recommendations provides a
wonderful opportunity to prevent cancer and improve global health. Individuals and
populations have in their hands the means to lead fuller, healthier lives.
Triacylglycerol metabolism inSaccharomyces cerevisiae was analyzed quan-titatively using a systems biological approach. Cellular growth, glucose
uptake and ethanol secretion were measured as a function of time and used
as input for a dynamic flux-balance model.
The AMP-activated protein kinase is an evolutionarily conserved hetero-trimer that is important for metabolic sensing in all eukaryotes. The muscle-specific isoform of the regulatory c-subunit of the kinase, AMP-activated
protein kinasec3, has a key role in glucose and fat metabolism in skeletal
muscle, as suggested by metabolic characterization of humans, pigs and
mice harboring substitutions in the AMP-binding Bateman domains ofc3.
The kynurenine pathway of tryptophan catabolism plays an important role
in several biological systems affected by aging. We quantified tryptophan and
its metabolites kynurenine (KYN), kynurenine acid (KYNA), picolinic acid
(PIC) and quinolinic acid (QUIN), and activity of the kynurenine pathway
enzymes indoleamine 2,3-dioxygenase
The hypothalamic neuropeptides modulate physiological activity via G pro-tein-coupled receptors (GPCRs). Galanin-like peptide (GALP) is a
60 amino acid neuropeptide that was originally isolated from porcine hypo-thalamus using a binding assay for galanin receptors, which belong to the
CYP7B1, a cytochrome P450 enzyme, metabolizes several steroids involved
in hormonal signaling including 5a-androstane-3b,17b-diol (3b-Adiol), an
estrogen receptor agonist, and dehydroepiandrosterone, a precursor for sex
hormones. Previous studies have suggested that CYP7B1-dependent metab-olism involving dehydroepiandrosterone or 3b-Adiol may play an impor-tant role for estrogen receptor b-mediated signaling.
Reactive oxygen species (ROS) are products of normal
metabolic activities and are thought to be the cause of many
diseases. A selenium-containing single-chain abzyme 2F3
(Se-2F3-scFv) that imitates glutathione peroxidase has been
produced which has the capacity to remove ROS. To
evaluate the antioxidant ability of Se-2F3-scFv, we con-structeda ferrous sulfate/ascorbate (Vc/Fe
)-inducedmito-chondrial damage model system and investigated the
capacity of Se-2F3-scFv to protect mitochondria from oxi-dative damage.
Lecture Biology - Chapter 6 provides knowledge of energy, enzymes, and metabolism. In this chapter, students will be able to understand: What physical principles underlie biological energy transformations? What is the role of ATP in biochemical energetics? What are enzymes? How do enzymes work? How do enzymes work?
Enzymes that function within plants, animals, and microorganisms are fundamental to
life, and their contributions to metabolic pathways and processes have been studied extensively.
For over 100 years there has been interest in what today is called ecological or
environmental enzymology. This aspect of enzymology originates from the work of
Woods, who, in 1899, wrote about the survival and function in soil of plant peroxidases
following their release from decaying plant roots.
A global research community of scientists is teasing out the biochemical mechanisms that regulate normal cellular physiology in a variety of organisms. Much of current research aims to understand the network of molecular reactions that regulate cellular homeostasis, and to learn what allows cells to sense stress and activate appropriate biochemical responses.
Vitamin C (ascorbic acid) is a water-soluble antioxidant, constituting one among the most
prevalent dietary antioxidants found in fruits, vegetables and beverages. Dietary intake is
usually in the area of 100 mg/d, with a DRI-RDA of 75mg/d (men) and 60mg/d (women)
(National Academy of Sciences, 2000). Food items rich in vitamin C include bell peppers (ca.
120 mg/100g) and citrus fruits such as oranges (ca. 50 mg/100g) (Souci, 2000). Vitamin C
