Carotenoids - lipid derivatives, produce pigments in plants and animals , An accessory pigment, either yellow or orange, in the chloroplasts of plants. By absorbing wavelengths of light that chlorophyll cannot, carotenoids broaden the spectrum of colors that can drive photosynthesis. Porphyrins - lipid derivatives, a group of light-sensitive, pigmented, ringed chemical structures that are required for the synthesis of hemoglobin. Complexed with metals usch as iron in hemoglobin and chloroph...

MEASURE TOTAL VOLUME - ANSWERSAFTER RECEIVING A 24 HOUR URINE FOR QUANTITATIVE TOTAL PROTEIN ANALYSIS THE TECHNICIAN MUST FIRST EXPOSED TO LIGHT - ANSWERSFALSE RESULTS IN UROBILINOGEN TESTING MA OCCUR IF THE URINE SPECIMEN IS 4 BILIRUBIN - ANSWERSWHICH OF THE FOLLOWING URINE RESULTS IS MOST APT TO BE CHANGED BY PROLONGED EXPOSURE TO LIGHT? BACTERIAL CONTAMINATION WILL CAUSE ALKALINIZATION OF THE URINE - ANSWERSURINE SAMPLES SHOULD BE EXAMINED WITHIN 1 HOUR OF VOIDING BECAUSE AT 4-7C ...

What is hemoglobin composed of? - 4 heme, 4 iron, 4 globins What disorder does a defect in heme synthesis lead to? - Porphyria Porphyria - Deficiency in the enzymes of the porphyrin pathway leads to insufficient production of heme. The principal problem in these deficiencies is the accumulation of porphyrins, the heme precursors, which are toxic to tissue in high concentrations. What is methemoglobin? -Methemoglobin is a form of hemoglobin that contains ferric [Fe3+] iron and has a decreas...
