We hypothesized that the observed pattern reflected a substantial change in fetal metabolic state. The fetus does not synthesize glucose but depends on the maternal supply67,68. Similarly, maternally derived EFAs and long-chain polyunsaturated fatty acids (LC-PUFA), in particular DHA, are essential ...
1. Signal peptide (and a pro-peptide) gets cleaved off Many proteins that undergo transport through the secretory pathway have signal peptides of 15–35 aa. length located predominantly at their N-termini. They are often cleaved by various proteases ...

What part of the ribosome is important in catalyzing peptide bonds? What is the monomer (building block unit) of proteins? Which molecule is used primarily for providing building materials for cells? A. Glucose B. Water C. Starch D. Protein ...
Question: Alanine is the only alpha-amino acid that does not have a chiral carbon. (a) True (b) False Alanine:- Alanine is an alpha amino acid that helps in biosynthesis of proteins. It contains an amine group and a carboxylic acid group, both attached to central...
While hGFAP-positive precursor cells in the ventricular zone have been shown as a potential cell of origin for ETMR [46], a sole constitutive overexpression of Lin28A in these cells was not sufficient to drive brain tumor development, neither in the forebrain nor hindbrain. In line with these...
First, there is a β-cell–specific isoform of glucokinase that, together with the glucose transporter GLUT2 and low hexokinase activity, enables the β-cell to sense circulating glucose concentrations in the physiologic range of 2 to 20 mmol/L.[19,23] Second, β-cells are deficient in lac...
Since sucrose is a disaccharide, it must be broken down before your body can use it. Enzymes in your mouth partially break down sucrose into glucose and fructose. However, the majority of sugardigestion happens in the small intestine( 4 ). ...
Why do free amino acids not have peptide bonds? What is a free amino acid exactly? What makes an amino acid hydrophobic? a. polar R group b. non-polar R group c. positively charged R group d. negatively charged R group e. R group that disrupts protein secondar...
Gluconeogenesis is one of the important cellular processes in the body. Here are some clinical conditions in relation to this process: Glucosuria In hyperglycemia, the glomerular filtrate may contain more glucose than can be reabsorbed and this occurs when the venous blood glucose concentration exceed...
