It also helps to transport CO2 from the tissues to the lungs- Harper 28th197Transport protein: Hb, the transporter of oxygen is a tetrameric protein- Vasudevan 5th28Structural protein: Collagen is the most abundant protein in mammals the main fibrous component of skin, bone, tendon, cartilage teeth- Vasudevan 5th28Table Harper 28th569: Some Functions of Plasma ProteinsTransport or binding proteinsAlbumin various ligands, including bilirubin, free fatty acids, ions , metals , metheme, steroids, other hormones, and a variety of drugsCeruloplasmin contains Cu2; albumin probably more important in physiologic transport of Cu2Corticosteroid-binding globulin transoortin binds cortisol Haptoglobin binds extracorpuscular hemoglobinLipoproteins chylomicrons, VLDL, LDL, HDLHemopexin binds hemeRetinol-binding protein binds retinolSex hormone-binding globulin binds testosterone, estradiol Thyroid-binding globulin binds T4, T3 Transferrin transport ironTransthyretin formerly prealbumin; binds T4 and forms a complex with retinol-binding proteinTable Harper 28th271Examples of some important human animal hemoproteins Protein FunctionProteinFunctionHemoglobinTransport of oxygen in bloodMyoglobinStorage of oxygen in muscleCytochrome Cinvolvement in electron transport chainCytochrome P 450Hydroxvlation of xenobioticsCatalaseDegradation of hydrogen peroxideTryptophan pyrrolaseOxidation of tryptophanPeroxidaseOxidative enzyme
