    Study Notes

    Carbohydrate Metabolism

    • Glycogen synthesis (conversion of lactic acid into glucose) takes place in the liver and muscles.

    Gluconeogenetic Organs

    • Liver and kidneys are gluconeogenetic organs that produce lactic acid.

    Glycome Study

    • Glycomics is the comprehensive study of glycomes that includes genetic, physiological, and pathological aspects.

    Biological Information Encoding

    • Polysaccharide chains encode biological information based on their constituent sugars, sequences, and linkages.

    Medical Conditions and Carbohydrate Metabolism

    • Medical conditions that indicate the need to investigate carbohydrate metabolism include diabetes, hypoglycemia, and hyperglycemia.

    Enzyme Deficiencies

    • Aldolase deficiency is NOT associated with diseases related to carbohydrate metabolism.

    Blood Glucose Determination

    • Fasting for at least 8 hours is necessary for determining fasting/basal blood glucose.

    Blood Glucose Measurement Methods

    • The text does not mention the radioisotopic method for determining blood glucose.

    Hyperglycemia

    • Hyperglycemia is NOT observed in starvation (fasting) according to the text.

    Glycogen Synthesis and Blood Glucose Regulation

    • Glycogen synthesis refers to the conversion of glucose into glycogen to regulate blood glucose levels.

    Hypoglycemia

    • Insulin overdose can lead to hypoglycemia.

    Glucose Oxidase Function

    • The primary function of glucose oxidase is to catalyze the oxidation of glucose to gluconic acid.

    Ketonuria

    • Ketonuria is commonly found in diabetic ketoacidosis, starvation, and high-fat diets.

    Ketone Body Synthesis

    • Acetyl-coenzyme A plays a crucial role in ketone body synthesis.

    Oral Glucose Tolerance Test (OGTT)

    • The OGTT is indicated in suspected cases of diabetes or impaired glucose tolerance.

    Insulin Deficiency and Diabetes

    • Diabetic ketoacidosis can be a consequence of insulin deficiency in diabetes.

    Peptide C Significance

    • Peptide C is a marker of insulin secretion and is used to diagnose insulinoma.

    Physiological State and Carbohydrate Intake

    • The fasting state is associated with a decrease in carbohydrate intake.
